The Knights of Gryphonne is a Codex Astartes-compliant Space Marine Chapter of unknown origin and Founding. Since the destruction of their Chapter homeworld by the Tyranid Hive Fleet Leviathan in 997.M41 the Knights of Gryphonne have been a Crusading fleet-based Chapter. The Chapter fleet's last known location was in the Segmentum Tempestus near the Reductus Sector.
There is a controversy whether the primary Chapter color is orange or crimson. There are examples showing both colour schemes.
The Knights of Gryphonne wear orange Power Armour with a black Aquila and backpack. The Chapter deviates from the standard Codex Astartes Chapter colours in that it does not indicate the company affiliation on the armour.
The Knights of Gryphonne's Chapter badge is a black Gryphon rampant, similar to the badge used by the Howling Griffons, centred on a field of orange.
